dc.description.abstract Celestichthys margaritatus, a new genus and species of Danioinae, is described from a rapidly developing locality in the Salween basin about 70-80 kin northeast of Inle Lake in northern Myanmar. Males and females are strikingly colouful. It is apparently most closely related to two danioins endemic to Inle, Microrasbora rubescens and &quot;Microrasbora&quot; erythromicron. The latter species may be congeneric with the new species. The new genus is identified as a danioin by specializations on its lower jaw and its numerous anal fin rays. The colouration, while highly distinctive, seems also to be characteristically danioin. The danioin notch (Roberts, 1986; Fang, 2003) is reduced or absent, but the danioin mandibular flap and bony knob (defined herein) are present. The anal fin has iii81/2-101/2 rays. In addition to its distinctive body spots and barred fins the new fish is distinguished from other species of danioins by the following combination of characters: snout and mouth extremely short; premaxillary with an elongate and very slender ascending process; mandible foreshortened; body deep, with rounded dorsal and anal fins; modal vertebral count 15+16=31; caudal fin moderately rather than deeply forked; principal caudal fin rays 9/8; scales vertically ovoid; and pharyngeal teeth conical, in three rows
